3 Aug 1940The British submarine HMS Triad (Cdr. E.R.J. Oddie, DSO, RN), returning from patrol, encountered the outbound U-46 (Endrass) off Fedjeosen, north of Bergen. Triad surfaced at 22.30 hrs after failing to achieve a torpedo attack position and engaged U-46 with her 4 inch gun. Endrass decided not to respond and dived. Triad also dived and tried to track U-46, but both boats lost contact. HMS Triad was lost in action six weeks later.

There was another U-46 in World War OneThat boat was launched from its shipyard on 18 May 1915 and commissioned into the Imperial Navy on 17 Dec 1915. The Naval war in WWI was brought to an end with the Armistice signed on 11 Nov, 1918. Read about SM U 46 during WWI.
